A man identified as Edenilson Steven Valle was found dead in Demi Moore's swimming pool Sunday morning, a rep for the Los Angeles County Coroner’s Office told The Wrap.
According to TMZ, the 21-year-old man was found at the bottom of Moore's pool after apparently drowning.
The website reported a house party took place while the actress was away. Officials said that no one from her family was present, and that the party was not thrown by Moore or her kids.
Police also spoke to Us Weekly, saying that a maid was present in the morning and five people were in the house at the time of the incident, but they didn't suspect a huge party took place.
The man slipped and fell into the pool, and didn't know how to swim, officials said. No foul play was detected and the man was invited to the party by an assistant to Moore or her daughters, TMZ reported.
According to Digital Spy, Demi Moore responded to the incident, calling it an "unthinkable tragedy."
"I am in absolute shock," she said in a statement. "I was out of the country travelling to meet my daughters for a birthday celebration when I got the devastating news."
She added, "The loss of a child is an unthinkable tragedy and my heart goes out to this young man's family and friends. I ask that you please respect the privacy of all concerned during this sensitive time."
